Need help understanding my boat 2 batteries - solar and wind powered electrical system

Hi there,
There
are 2 batteries connected together, one for starting outboards and a
200AMP deep cycle one for the house, a solar panel and a wind turbine
(not functioning until I'll give it maintenance and replace blades).
Problem is for now that it seems even on a sunny day the solar panel
won't charge the house battery.
I haven't been able to try it while
running the 2 outboards.
I know that the
installation has been done few years ago by a professional (that didn't
label much things that I can understand) and seems to be all in good condition from my low
expertise level.
The solar panel is at least 10 years old but I have limited information as for everything.. It does look in good condition though (unlike the wind turbine).
On the DC METER, I can read
around 14.5-14.4V for both start and house battery when sunny without
anything turned on, also a discharge of 1.3-1.7A in those conditions,
and a charge of 0 no matter what I do playing with the different
buttons/settings available.
On the second picture, the left Amp
indicator is "ticking" hard when the sun hits and I have nothing on, but
still no power goes to my house battery.
I believe the second one showing -+30 amps could be wind turbine related?
Also
the starting battery shows a green dot saying it should be fully charged. The DC meter only gives me the house battery current
capacity. It does stay constant over days of everything turned off.
The last pictured item is in stand by no matter what, so I guessed this one could be going with the outboards running?
If
I turn on the water pump/lights or fridge I read a reduced voltage on
the DC Meter for both starting and house battery (believe they are
connected together, and heard from old owner that start battery should "overflow" when full to charge the house battery...)
I'm really keen on
learning how all these systems work and will be very thanksfull to anyone
taking the time to read me and give some advice!
Cheers

Pic 1 could be your eco charger ?
You need to figure out what battery is bank one and bank two , I’m thinking your start battery is batt# 2 .
An older battery, can by voltage alone, appear to be fully charged but actually has little capacity, load testing would establish this. There appears to be a selective relay between the start and house battery, which is common on boats along with RV applications so as not to drain the starter battery with house loads, personally I believe it's best to keep both systems divorced from on another to eliminate uncertainty.
The inclusion of wind power only complicates matters, attempting to reverse engineer someone else's Frankenstein wouldn't be something I would not be willing tackle, especially without being on site, for this reason I suggest starting from scratch and keeping records including wiring diagrams so you remember what it is you did.
As I have no idea of your personal level of experience, it's difficult to offer suggestions other than those outlined, what may have made sense to the original installer dosent nessersary translate to others.
Second system 1890W 3 × 300W No name brand poly, 3×330 Sunsolar Poly panels, Morningstar TS 60 PWM controller, no name 2000W inverter 400Ah LFP 24V nominal battery with Daly BMS, used for water pumping and day time air conditioning.
5Kw Yanmar clone single cylinder air cooled diesel generator for rare emergency charging and welding.
And sadly, the wiring rats nest/tangle is about as bad as the contents of my junk wire box. The whole thing, since it's not working right, and nobody knows what the original intent / scheme was, is to redo the the thing. Sorry. That's the right way to fix it.
